Docs show incorrect hex information (?)

[gamma-delta]

Hello,

The front page for the documentation has some ASCII art of the two hexagon styles, showing the coordinates for pointy and flat-topped hexagons.

However, I think these diagrams are wrong. They both show that the cube coordinates increase in the direction of the corners, not the sides. I think you've mixed up the coordinate diagrams for the two styles...

(Also it would be nice if there was a nice SVG or something instead of the ascii but that is kind of bikeshedding)
